Wavelength is a measure of distance, typically expressed in meters. However, when you refer to "one second" in the context of wavelength, it's not clear what exactly you are referring to.
A second is a unit of time, representing a duration or a period. It does not have a direct conversion to a wavelength. Wavelength is associated with the propagation of waves, such as electromagnetic waves or sound waves, and represents the distance between two corresponding points on the wave, such as two adjacent crests or two adjacent compressions.
If you could provide more context or specify the type of wave you are referring to, I can try to provide a more specific answer regarding the wavelength associated with that wave.
